This is the report of the First Great Buttosaur Expedition, led by Dr. Andrew Griffiths with the addition of the drawings made by Dr. Terrence Denton. It was issued because future expeditions are on hold given the threat posed by the Fartosaurus, that has no natural enemies. It is "capable of descending on prey and smothering it whole in a silent but deadly manner." This is a well-written report and easily used by serious students, who will find the 'vital statistics' offer a succinct description on each creature. Students facing a deadline should first read the introduction and then use the index to prepare their report or presentation in twenty minutes or so. A sure-fire A!
